Management Zone Analyst (MZA) is a decision-aid for creating within-field management zones based on quantitative field information. It mathematically breaks up a field into natural clusters or zones based on the classification parameters and number of zones you specify.

Root Zone Water Quality Model 2 (RZWQM2) is a whole-system model for studying crop production and environmental quality under current and changing climate conditions. It emphasizes the effects of agricultural management practices on physical, chemical and biological processes. RZWQM2 is a one-dimensional model with a pseudo 2-dimensional drainage flow. Crop simulation options include the generic plant growth model, DSSAT-CSM 4.0 and HERMES SUCROS models. It also can simulate surface energy balance with components from the SHAW model and water erosion from the GLEAMS model. An automated parameter estimation algorithm (PEST) was added to RZWQM2 for objective model calibration and uncertainty analysis.

The Uniform Soybean Tests, Northern Region, in place since 1941, evaluate yield, disease resistance, and quality traits of public breeding lines from northern states of the USA and Canadian provinces. The annual reports which compile the test results (PDF format) are available, and new reports are added annually.

Product system boundaries (cow-calf-finisher, CCF) include all material and energy flows associated with crop production and live cattle operations. Cattle inventory flows include the cow-calf operation and end with market weight finisher cattle and culls resulting from one full year of operation. The total live weight produced in one year is 2914841.44 kg and is comprised of the following animals: Finished cattle: 3724 (581 kg/finisher), Culled cows: 1156 (636 kg/cow), Culled bulls: 58 (908 kg/cow). These data were developed using Integrated Farm System Model and are intended to represent the MARC cattle operation in Nebraska in 2011. The data were a product of a project funded by the National Cattleman's Beef Association.
